Bit 13: Command_Acknowledge –
Normally “0”. This bit is set to “1” when one of the following com-
mands completes successfully:

Preset Position

Reset Errors
This bit resets to “0” when the command bit is reset to “0” by the host controller.
Bit 12: Absolute Encoder Error –
This bit is set to “1” under the following conditions:

The shaft was subject to acceleration in excess of 160,000°/sec
2
(444.4 rev/sec
2
) while power
was removed from the unit

The internal battery is fully discharged or damaged

The encoder itself is damaged
If this bit is set, cycle power to the unit. If the bit remains set, contact AMCI technical support for
assistance.
Bit 11: Heartbeat_Bit – This bit will change state approximately every 500 milliseconds. Monitor this bit to
verify that the unit and network connection are operating correctly. Note that this bit is only available
while the SV160E2 is in Command Mode.
Bit 10: Torque_Limit – This bit is set to ‘1’ when a torque limit is active during the move. In typical cases,
this is the Peak Torque Limit during the acceleration and deceleration phases of the move and the
Continuous Torque Limit during the constant speed phase of the move. If the Maximum Move
Torque is set as part of the move command, this value is used through all of the phases of the move.
Bit 9: Invalid_Jog_Change – Set to ‘1’ during a Jog Move if parameters are changed to invalid values.
The Jog Move continues with the old parameter values. This bit is reset to ‘0’ when the parameters
are changed to valid values. Parameters that can be changed during a Jog Move are Programmed
Speed, Acceleration, Deceleration, and Maximum Move Torque.
Bit 8: STO_Failure – This bit is only available on SV160E2-STO units. Reset to ‘0’ during normal opera-
tion, this bit is set to ‘1’ if the programmable STO Discrepancy Time Limit is exceeded. This indi-
cates a failure in the normal operation of the STO circuit. This fault is non-clearable. Power must be
cycled to the SV160E2 to clear this fault.
Bit 7: Driver_Fault – This bit is set to "1" to indicate faults in the driver section of SV160E2, such as Over-
temperature or Overcurrent Faults. If you are using an SV160E2-STO, this bit is set if either or both
of the STO inputs are inactive. Driver Faults are self clearing. This bit will reset once the fault condi-
tion is removed.
Bit 6: Connection_Was_Lost – If the physical network connection is lost at any time, this bit will be set
when the connection is re-established. Note that this bit is not set if the communication loss is on the
protocol level, not the physical level.
Bit 5: STO_Active – This bit is only available on SV160E2-STO units. Reset to ‘0’ during normal opera-
tion, this bit is set to ‘1’ if either or both of the STO Inputs become inactive. This bit indicates that
the STO feature is active and power has been removed from the motor driver section. This bit auto-
matically resets to ‘0’ when power is reapplied to both of the STO inputs. An Enable Driver com-
mand must be issued before power is restored to the motor. Note that issuing an Enable Driver
command while this bit is active will result in a Command Error response. The data format of the
Enable Driver or Preset On Enable command can be found on page 68.
Bit 4: Temperature_Above_90°C – This bit is set to “1” when the processor internal temperature exceeds
90°C. If this bit trips often and you want to lower the operating temperature of the unit, consider
changing how the device is mounted, or installing a fan to force additional airflow over the device.
